Beit known that il, RALPH `Heirs Asiinii,

a citizen ofthe UnitedStates, yand a resident of London, in thecounty ofMadison and State of Ohi`o,ih'ave invented a new and I useful`linpfroveineiit in-` Air "Regulators, of

which the following is a full, clear,'and ei:-

4An object'of my inventionis to provide a 'devicewhiohwill'automatically regulate or control the amount ofv air 4entering theycarburetor,`in such anianner that the fuel whichis consumed `byaninternal combustion engine, operated in connection with thecarburetor, is considerably 'lessthan where sucligair regulation is notused. y i f A further Aobject of my invention is to `provide an airregulator of the Vtype de-` scribed, which'is made inthe form of an unitthat may be" inserted in the air' intakepipe leading to the carburetor,without the neces sity of changing or altering either the pipe orthe'carbureto'r.

My invention is illustrated in the accompanying drawings, Vforming partof this application, in which-` Fig. l is a side view of a carburetorand an intake pipe leading thereto, the position of the air regulatorbeing shown in dotted.

lines,

' Fig. 2 is a plan `view of the air regulator,

' 'Fig 3 is a sectional view through a por` tion of the air intake pipe,the carburetor connection, and the air regulator, and

Fig. 4 is an end view of the air regulator.`

ln the drawings,y the air intake pipe is indicated at 5this beingprovided with an the exhaust pipe?, as in the ordinary Ford engine, forthe purpose of heating the `in-\ 'opening nppiieanon ined January e,i921. senai no. 434,566.

coming'air. The carburetor 8 isrprovided with the usual pipe connection`9 adapted .to receivethebent end of the intake `pipe 5. Theairregulator is made in the form of llt' consists of a short tube 'l0havi a unit.`

ing a lateral ,eiiteiidingend flange 1l, fthe` widthof this `flangebeing substantially i thatof the thickness of'thewall of the intakepipe'5,`as'shown in Fig. Theopposite end of the tube is-beveledandfisprovided with an inclined end portion 12, which has anopenin'g 13therein.

purpose explainedy hereinafter.,l Ears 16 eX- p The top portion of thetube 10 has arecess l5 for a tend forwardlyfroni'the beveled end of thetube lOand between these ears is `thepivot pin 17 of a weightedvalveilSLThis valve *i is made preferably in theshapeshown in thedrawings and isprovided with aflat face arranged to abut the inner side of the endportion 12 so as to normallyclose the lead orwofanyv suitable material.

:ein the `'foregoing' "description `of the vvarieus parte of the device,the'` operationy thereof may be readily understood.y pll'n Figf 'rires-land 3 3the'valve is shown closed. lt

will be observed that there isa passageway r for lair through"theopeningl5 and between rthe upper surface of the valve `l2 on the inner wall ofthe intakepipe 5.` Vhen the` engine is cranked, air will enter throughvthe opening lfandwillvpasson to the carburetor, inixingwith thefuel andbeing drawn into the cylinders of the engine.` Assoon y 3. Jillhe valvemay ybe made of! r as the engine starts," the suction of the en-vQiiiewill cause the valve l2 to `move away from its seatgthus uncoveringthe opening 13. The greater the sneed of the engine, thev farther thevalve will move, thus allowing vincre air to enter. lhave'found'byexperiinentthat thisair control device actually saves aconsiderable amount of fuel in an internal combustion engine, `such asthe Thus, whenan engine with-` out my improved air regulator' isthrottled down to a given point, the engine will stop,` whereas underthe sanie conditions, with` Ford engine.

'my air regulator, it will continue to'run.

`,f-igai'iii, I havefound thatwith my air reg` ,ulatoig the engine willstart, where it will `not start under the, same conditions withy out theair regulator. When iny regulator isy used the needle valve ofthecarburetor may `be turned to a point which will more nearly close offthefloW 'Qf ,fuel than is possible,`
